计入空化效应的新型动静压轴承热动力分析（Thermohydrodynamic Analysis on Novel Journal Bearing Considering Cavitating Effects）
动静压轴承 螺旋油楔 热动力 空化效应 两相流模型
2010/4/1
基于气液两相流空穴模型，建立了螺旋油楔动静压轴承的热流体动力润滑数学模型。采用有限差分法，数值求解了广义雷诺方程、简化油膜能量方程及轴瓦热传导方程，研究了油膜压力分布以及供油温度和供油压力对轴承内表面温度的影响。结果表明：油膜破裂面积沿轴向先减小后增大，破裂位置沿圆周方向有一定的偏移，距离的大小与螺旋角有关；供油温度对轴承内表面温度的分布影响较大，而供油压力的影响相对较小。 Based on th...
